RE: Shooting lanes...

Although everyone is right about scent control et.all...it does come down to what the deer are use to in your area.
In some areas, deer are use to some human presence in the woods, in these cases, I do not think you would have much of a problem cutting lanes now.
However, in other areas, where human presence is non-existent or extremely minimal, I would not recommend that you go in there until opening day.
